The girl was contemplating the specious beauty of it all, when on the breeze from seaward came a shout. She turned quickly. There was Dick up to his knees in a rockpool a hundred yards or so away, motionless, his arms upraised, and crying out for help. She sprang to her feet.
There had once been an islet on this part of the reef, a tiny thing, consisting of a few palms and a handful of vegetation, and destroyed, perhaps, in some great storm. I mention this because the existence of this islet once upon a time was the means, indirectly, of saving Dick's life; for where these islets have been or are, "flats" occur on the reef formed of coral conglomerate.
Emmeline in her bare feet could never have reached him in time over rough coral, but, fortunately, this flat and comparatively smooth surface lay between them.
"My spear!" shouted Dick, as she approached.
He seemed at first tangled in brambles; then she thought ropes were tangling round him and tying him to something in the water--whatever it was, it was most awful, and hideous, and like a nightmare. She ran with the speed of Atalanta to the rock where the spear was resting, all red with the blood of new-slain fish, a foot from the point.
As she approached Dick, spear in hand, she saw, gasping with terror, that the ropes were alive, and that they were flickering and rippling over his back. One of them bound his left arm to his side, but his right arm was free.
"Quick!" he shouted.
In a second the spear was in his free hand, and Emmeline had cast herself down on her knees, and was staring with terrified eyes into the water of the pool from whence the ropes issued. She was, despite her terror, quite prepared to fling herself in and do battle with the thing, whatever it might be.
What she saw was only for a second. In the deep water of the pool, gazing up and forward and straight at Dick, she saw a face, lugubrious and awful. The eyes were wide as saucers, stony and steadfast; a large, heavy, parrot-like beak hung before the eyes, and worked and wobbled, and seemed to beckon. But what froze one's heart was the expression of the eyes, so stony and lugubrious, so passionless, so devoid of speculation, yet so fixed of purpose and full of fate.
From away far down he had risen with the rising tide. He had been feeding on crabs, when the tide, betraying him, had gone out, leaving him trapped in the rock-pool. He had slept, perhaps, and awakened to find a being, naked and defenceless, invading his pool. He was quite small, as octopods go, and young, yet he was large and powerful enough to have drowned an ox.
